This invention relates to a mast such, for example, as is adapted to suportl an aerlal, and 1s particularly concern with certain features ofconstruction by which it may be produced at small expense, be set up in`any one of several positions of adjustment, and be attachable `to wallsor roofs of widely varying kinds. In the attainment of these.

objects, we associate with the mast a base having a detachableconnection therewith, such as to permit of the base occupying any one ofseveral different ositions of a justment relative thereto. y this vmeansthe mast can be mounted u on a vertical wall or post, a horizontal or santing roof, a gable peak, or elsewhere.

An embodiment of our .invention in its preferred form is shown in theaccompanylng? drawing in the manner following igure 1 is a sideelevation of the lower mast end together with base attached thereto.

Fig. 2 is a vertical section taken online 2-2 of Fig. 1;

Figs. 3 and 4 which are perspective views show the mast as attached'to avertical wa or support;v

Fig. 5 shows in perspective the mast as mounted on a flat roof;

Fig. 6 which is also a erspective view shows the mastras securedp uponthe peak or ridge of a gable roof; and

Fig. 7 also s ows in perspective a mounting of the mast upon a slantingroof.

The present structure comprises two units, viz, a mast A which isconnected by bolts or otherwise to a base B. These parts are preferablymade ofmetal, the mast being shown as having a T "section, and the baseo being built up from a pair of plates or sheets. The two components ofthe base are counterparts of each other, each comprising an outturnedflange 8 from which is obliquely extended an angular section 9 which 5terminates in a supporting section 10 having a right an ulardisp'ositlon relatlve to the flan 8. e thus 'provide a structure havingtween the two sections 9 an angle of 90 or thereabouts which adapts thebase to be seated upon a corner su port or elsewhere, orto present itstwo anges for securement to a fiat surface, as will more clearly ap arhereinafter. One end 11 'of each of t ese three Vsections is mutually "5aligned, and preferably in righangular re shown) are provided in readilybe appreciated by lationto the adjoining edges 12 and 13 of the flan eand supporting sections respectively. e opposite ends 14 of these threesections,however, which are also in mutual alignment, are preferablyslanted toward the other end 11 as it proceedsv upwardly from the flangesection.

Two base components of this general character are 'arranged incomplementary manner with the two supporting sections side by sidewhereby the angular sections 9 diverge downwardlyto present the fiangeSections 8 in spaced relation. The assembly of the two base componentsmay be completed with the aid of bolts or screws 15. These are enteredthrough registering openings of which four are provided, one proximateto each corner of the supporting sections. In addition, we provide otheropen lngs 16 in the angular sections and still ot er openlngs in theflange sections permitting the lnsertion therethrough of fasteningdevices, such as are suitable for securing the base to a Wall,-roof, orother support. 80

With a base of this general description, we associate the mast A which,as before stated, is preferably of T section with a head 18 and web 19.The mast web may be entered between the two supporting sections 10 alongan one of its three edges 11, 13, or 14, in Whic position the head 20may also engage therewith. A pair of openings not the mast an so spacedas to register with any twopadjacent openings in the supporting sectionsof the base whereby the fastening bolts or screws may pass through themast web to effect a securement to the base. By this means we areenabled to attach the mast to the base in a manner which is both simpleand rigid.

Certain of the advantages resulting from the construction heretoforedescribed may reference to Figs. 3 to 7 inclusive, wherein isrepresented various conditions of installation. In Fig. 3 for example,we have shown the base secure to a vertical wall with the mast attachedalong the edge 13 of the base. In Fi 4, where the same assembly is used,the ase is shown as connected to a corner post of a building structure.In Fig. 5 the base is seated upon the peak or ridge of a gable roof andin Fig. 61it isj secured upon a fiat surface. .In each of these last twofigures the 110 mast is assembled along the front end 11 of the base.Fig. 7 shows the mast mounted upon a slantmg roof, and connected withthe basealong its rear edge 14. In this manner, the mast is supported ina substantially `upright position even though the. base be end of eachrod is secured to the building construction at a desirable place.

The present invention is meritorious in many respects, notably in thesimpllcit of the structure, the economy with whic it may be produced,the ease with which it may be set up and installed, and the severaladjusted positions which it may occupy with relation to its base.Because of features such as these, the mast will satisfactoril fulfillall the usual conditions, and serve e fectively for its intendedpurposes.

We claim 1. A mast of T-iron having a base with two plates arranged onopposite sides of the mast web whereby the mast head may engage with oneedge of each plate, there be- 1n a plurality of openings through themast weil) and the two plates so arranged that those of the mast mayregister with certain of those in the plates which are proximate to one4ed e `of each, and means extended through t e registering openings ofthe mast and base in a manner to secure ,the one removably to the otherin a selected position of adjustment, substantially as described. i

2. In combination, a mast and a two part base of sheet metal, the mastbeing formed with a web adapted to lie between the base parts and with ahead for en aging with one edge of each, and means w ereby the mast maybe removably secured to the base along any one of three edges thereof,substantially as described.

3. In combination, a mast and a base therefor consistin of twocomplementa lates arranged si e by side, means exten mg laterally fromthe mast between the plates proximate to a securing edge thereof wherebya portion of the mast remaining exteriorly of the plates may engage withsaid edge and be supported in a-llgnment therewith, connecting meansextended through the ltwo lates and laterally extended portion of t emast in a manner to secure the one removably to the other, the masthaving 00 three such 'securing edges, one in right angular' relation toanother and the thirdobliquely disposed to the other two whereby themast may be connected to the base in alignment with any one of saidthree edges,

substantially as described.

4. In combination, a T-iron mast and a double plate base adapted toengage the mast flange upon opposite sides, each base plate having asecurin section with three free' 'l0 edges, one vertica one horizontal,and the other disposed obliquely to the other two, there being in themast web two openin andy in each base plate four openings simllarlyspaced in consecutive order, one proxi- 'I5 mate to each end of saidthree edges, and means passing through two adjacent holes of each plateand through the mastl holes to connect the mast removably to the basealon an selected of the threefree edges thereo su tantially asdescribed.
